JavaScript Program to Multiply Two Numbers

Introduction

Multiplying two numbers is a fundamental arithmetic operation and can be easily performed in JavaScript using the * operator. This guide will walk you through writing a JavaScript program to multiply two numbers.

Problem Statement

Create a JavaScript program that:

• Accepts two numbers.
• Multiplies the two numbers and returns the result.

Example:

• Input: 5 and 3

• Output: 15

• Input: 7 and 4

• Output: 28

Solution Steps

1. Read the Input Numbers: Provide two numbers either by user input or directly in the code.
2. Multiply the Numbers: Use the * operator to multiply the two numbers.
3. Display the Result: Print the result of the multiplication.

JavaScript Program

// Author: https://www.javaguides.net/

function multiplyTwoNumbers(num1, num2) {
    // Step 1: Multiply the two numbers
    const product = num1 * num2;
    
    // Step 2: Display the result
    console.log(`The product of ${num1} and ${num2} is: ${product}`);
}

// Example input
let number1 = 5;
let number2 = 3;
multiplyTwoNumbers(number1, number2);

Explanation

Step 1: Multiply the Two Numbers

• The numbers number1 and number2 are passed as arguments to the multiplyTwoNumbers() function. Inside the function, the * operator is used to multiply these two numbers.

Step 2: Display the Result

• The result of the multiplication, stored in the variable product, is displayed using console.log().

Output Example

The product of 5 and 3 is: 15

Example with Different Input

If you modify the input to:

let number1 = 7;
let number2 = 4;

The output will be:

The product of 7 and 4 is: 28

Conclusion

This JavaScript program demonstrates how to multiply two numbers using the * operator. This simple arithmetic operation can be used in various programming tasks, and the program provides a straightforward way to perform multiplication in JavaScript. By following this method, you can easily extend the program to handle user input or more complex mathematical operations.
